1. Remove the old finish
Removing the old finish is the very first step to refinish your wooden furniture. This is also likely the messiest and most tedious part. There are actually two methods for doing this task – sanding and chemical stripping.
Also called paint and finish strippers, chemical strippers are considered the most effective products to remove varnish and paint from wooden furniture.

- Chemical wood finish and stain stripper
- Dust mask
- Eye protection
- Scraper tool or putty knife
- Steel wool
Make sure you have enough and proper ventilation no matter where you are working since it can be dangerous to inhale chemicals.
Take note that for most purposes, you will also want to go for a thicker formula such as a paste or gel. A liquid paint stripper is going to run and you can only use it on horizontal surfaces. The easier and quicker alternative for a smaller project is an aerosol spray stripper.
Always follow the manufacturer’s instructions when you use the paint stripper. In general, however, you should apply the stripper in a thick coat then wait for some time as stated on the container. Use a scraper tool or putty knife to remove as much varnish and paint as possible and wipe your tool’s blade between scrapes. Steel wool can be used as follow for tougher areas as needed.
Let the wood dry completely before you proceed to the second step.

- Use the palm sander of 80 to 150 grit for removing majority of the finish.

- Use the palm sander of 150 to 200+ grit to remove the remaining paint or stain until the entire piece is bare.
You can use a tiny piece of sandpaper or sanding block to complete the job for places that are impossible or awkward to reach using the sander.
